Javascript : Uncaught ReferenceError: function is not defined

Question

I have a function in a JS file that allows me to perform a select on a Web SQL database of my browser. When I display my page the browser console tells me that the function does not exist. I confess I do not understand because she is present there. I have other functions that I use in this same file and that works correctly. the error i get :

Your file is probably poorly loaded, I tested your code, the function is well executed. You say that other functions work properly but they are in another JS file, check if your file is found.
